•If not connected to the thermostat, turn the switch to (ON).

When unit is started for the first time or is started after the oil

tank has been totally emptied, the flow of oil to the burner may

be impaired by air in the circuit. In this case the control box will

cut out the heater and it might be necessary to renew the starting

procedure once or twice by depressing the reset button (1).

Should the heater not start, check that oil tank

is full and depress reset button (1).

Should the heater still not work, please refer to chapter
